SAS Tips: Readin a special text file

Posted by phillippeng on November 19, 2008

Problem: Read in a kind of special text file into SAS. I say it is special because it’s at least not covered in the popular book “The Little SAS Book”. Each field in the input text file is enclosed with double quotation marks and is separated by comma.

Challenge: Get rid of the double quotation marks for each field

Solution:

filename file1 “..\file1.txt”;
libname home “&path.\Data”;

data home.data1;
infile file1 dsd dlm=’09’x missover lrecl=225 firstobs=2;
format     var1    $90.
var2    $40.
var3    $25.
var4    $2.
var5    $5.
var6    $4.
var7    $4.
informat     var1    $90.
var2    $40.
var3    $25.
var4    $2.
var5    $5.
var6    $4.
var7    $4.
;
input @;
_infile_ = tranwrd (   substr (   _infile_
, 2
, length(_infile_) – 2
)
, ‘”,”‘
, ’09’x
);
input       var1      $
var2      $
var3      $
var4      $
var5      $
var6      $
var7      $
;
run;

Key point: Use “_infile_” and tranwrd function.
